Personal Statement

My practice focuses on treating gastrointestinal malignancies, including colorectal, pancreatic, stomach, biliary, neuroendocrine, and liver cancers. I place great value on having strong physician-patient relationships and feel this is especially important in cancer care. I not only provide state-of-the art cancer treatment for my patients and their families, but comprehensive support through a compassionate and multidisciplinary approach. Through clinical research, I am able to offer my patients access to the latest therapies such as radiolabeled monoclonal antibodies, cancer “vaccines,” immunotherapy, and other novel targeted agents. At Weill Cornell Medicine and New York-Presbyterian Hospital, we utilize a bench to bedside approach and are committed to bringing the most promising new treatments out of the lab and directly to patients often years before they are widely available elsewhere.
